If UPS lost it, assuming Bitmain insured it correctly they would be reimbursed by UPS.

Should be fair to refund customer.

If unit was received is different as they will warrant a replacement for anything defective.

Tell that to Bitmain.

If UPS loses a delivery, how do they reimburse Bitmain? I guess it depends on how Bitmain insures the shipment, if at all. I know they send via UPS World Saver but I'm sure insurance is optional. Does UPS have an automatic minimum insurance included??? I don't know.

Let this this a cautionary tale to you all. If and when UPS loses your miner package, you are SOL in terms of getting your btc back. Even Bitmain doesn't play fair when it comes to it.

In my experience of buying mining hardware Bitmaintech.com has been the best. They are quick to respond to questions and orders are shipped out fast after the payment is received. I look to Bitmaintech.com first when gearing up to invest in new hardware and hope they continue to be successful and offer these top products. BTC

So, your point is that I should just take whatever they offer?


    I am not sure what his point is. but the only refunds I have seen them give were if someone overpaid.

 Lets say you sent .6 btc for a .5 btc machine.
 I have not read of many refunds for a problem like yours.  The offer they gave you is not that good.

 Ask them for the replacement and a second one for .3 btc  

Then list the two for .8btc  your loss will be less.  but I hear your compliant and have some sympathy as I got a dud back in feb.

 if it were not for bobsag3 giving me a replacement  up front then waiting for me to send him a the dud. the exact same thing would have happened to me.

Well, I couldn't wait another day, so I emailed Bitmain asking to get my BTC back. It cost 0.554 BTC when I ordered it on April 30. I don't want a replacement unit because I've already lost 2 weeks of mining as a result of UPS losing it. Even if Bitmain offers me a coupon to cover the price difference, I don't see any point in getting another S1.

Let's see if Bitmain comes through for me.

In these case they are always trying to give you another unit + a lot of useless coupons (maybe not totally useless now cause you can sell to other users)

Yep, just received an email from bitmain, they are offering me "a new miner tomorrow and offer you 3 x 0.05btc coupon", now how should I respond? I mean, I thought I had already made clear to them that I don't want a replacement unit, I just want my btc back at this point.

Do I keep insisting on getting my btc back? Or, just take the offer?

they will not give you a refund.  sad but true.

 Ask them for the replacement  miner  and ask if you can buy a second miner for 0.3btc.  

    this would mean you got 2 for a total of 0.854btc.

  which is a fair price  for 2 machines at todays price.

Yes, sad but it's true, they just won't refund. It looks like I will be getting a replacement S1, instead of 0.554 BTC. As for asking for another S1 for 0.3 btc, I just don't NEED or WANT another S1. I've already maxed out. Even the replacement unit is questionable at my place, I may have to sell it. Because UPS lost it, I will be out at leat 0.1 btc, assuming I can sell the coming replacement S1 for 0.4 btc, which may not be realistic.

Imo I would insist for refund.

Why shouldnt they refund?

yeah the lightning 1300 is good and I considered it to be the best deal… up until now. 

 right now  the evga's  1300's  are best for 3 s-1's or 1 s-2/


http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1400419758&sr=8-1&keywords=evga+supernova+1300


195 and the 15 dollar rebate= 180  10 year warranty.  they pull 1215 watts for 3 s-1s at 393 freq. 600gh

I agree.  That's a fine PSU for $180.

Consider the efficiency of these units 70-75%?   and you can calculate power savings 6 months or a year down the road if you are using to mine btc 24 hours a day.

Ive not used that specific unit but I haven't come across a server grade psu made in the last 3-5 years that has been below 88% efficiency personally.

As we know psu highest efficiency is most likely at 50% load and not as efficient at 20% or 100% load.

You can see here alot of comparison of name brand server psu:  http://www.plugloadsolutions.com/80PlusPowerSupplies.aspx

You will notice the majority is at Bronze 85% and less.  And at lower load 20% or highest load 100% Brozne 85 is only about 81-82%

The second highest category is regular Bronze only 80% efficiency.

This is not even including the many many server psu on the market that dont even have a 80 Plus rating (probably Chinese, or fake) :  so they are much less and into the 70% range obviously.

You are correct I tested my Dell server PSUs and they use 860-870watts per 2 S1s at the wall. This is the exact same as my thermaltake bronze PSU. My EVGA and Corsair golds use exactly 800watts at the wall for the same 2 miners. Doing the math the difference per month in electricity would take a long time to offset the initial savings savings of buying a server PSU.

The 60 watts savings for the Gold psu per day at .16 per kwh running 24/7 for a year would save $84

For platinum about $125 a year.  

Amazon for $170 Platinum Corsair 860  http://www.amazon.com/Corsair-Professional-860-Watt-Platinum-AX860/dp/B00A0HZMKG/ref=sr_1_1?ie=UTF8&qid=1400395186&sr=8-1&keywords=corsair+platinum+860

So $45 for plat psu 860 watts and great resale value I think is good deal

Wow, $170 for a 860 watt PSU.  Spend $240 and get a 1300 that can drive 3x OCd S1s.  Pulls about 1025W at the wall @ 115V.  I used three of these for my 9 S1s.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063

EDIT: My memory was wrong.  From an earlier post of mine:

I'm using the Lightning 1300 here.  According to my Kill A Watt, 3 of them OCd pull 10.65 amps @ 114v using 1212 watts.

yeah the lightning 1300 is good and I considered it to be the best deal… up until now.

  same results as you the dell servers are power hogs compared to any good platinum psu.   or this one it is gold but runs 3 ants a freq 393.

http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1400411011&sr=8-1&keywords=evga+supernova+1300

on sale for 195 at amazon with a 15 dollar rebate form.  so 180 to run 3 ants.

it pulls 1215 watts   if you run 3 ants at 393 freq just about 600gh.

the dells would do more then 1290.    the dells have a real shock issue.  as wires are more exposed.  the dells are real bleeping loud.

Fixed I meant to say my Platinums use 400watts per overclocked S1 at the wall. Also, buy used Platinum PSUs on ebay for cheap

so whats the consensus on a PSU for the ants / what's the most popular choice...? what sort of wattage do you need for factory and / or OC'd units...?

If you have some spare time for modding, server psu is the cheapest choice that you can find (Dell PSUs are the most used)

i really don't have any time to dedicate to modding... just looking for a cheap PnP... what wattage is recommended for factory or OC'd ants...?

It's not so much wattage, it's amperage on the 12V rail.  An OC'd S1 uses about 32-33amps on a gold PSU on a 115v line.  Make sure whatever you get has enough juice on the 12V line to run as many Ants as you are looking for, and you should be fine.

M

so if i were looking @ something like this http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139060 would that cover the power source needed to run a factory ant? what about an OC'd ant?

I can't tell.  There are no specs about the 12V rail.  I'd proceed with caution.

If you intend to drive more than one ant, and are prepared to spend $100 on a decent PSU, consider this one:

http://www.newegg.ca/Product/Product.aspx?Item=N82E16817182063

Will drive 3xOCd S1s with room to spare.

M

can't shell out that much thats for sure... i'd rather not hook up more then one ant to one psu... so i would need about 6-8 psu's total... anything recommendations in the $100 range if possible would be appreciated...

3 PSU = 3 power cords, 3 boxes, and extra cables

If you're going to do $100 a PSU, the one above will save you $70 right out of the box.

However, as others have said, there are cheaper ways to do it.

M

Here is the one:

http://www.ebay.co.uk/itm/IBM-74P4453-Bladecenter-E-2000W-Power-Supply-zj-/261410878512?pt=US_Network_Switch_Power_Supplies&hash=item3cdd4d7430


Price is so low its almost stealing.
Cables will be near nothing and only time to mod this one. This one will run 4 miners OC.

Consider the efficiency of these units 70-75%?   and you can calculate power savings 6 months or a year down the road if you are using to mine btc 24 hours a day.

Ah.  I was going to say, at 115v, 4 S1s OCd will blow your 15A breaker.  But I see you aren't talking about the US.
